generating dynamic heading images

[duncan.lovett]

I want to generate dynamic heading images, but I won't be able to use
the GD Library, ImageMagick or any other plug-in to generate an image
on the fly due to hosting restrictions.

I have seen, in the past, sites that generate headings from a set of
Gif images, each corresponding to a letter in the string that is being
turned into a graphical heading.

I've searched in vain on a technique on how to do this, but all I can
find is the GD technique of FIR (Flash Image Replacement).

Before I have to sit down and have a think about how to achieve this
solution, does anyone know how to do this or know of a site with a
tutorial on how to get the result I require?

I need to - break a string apart an then count the individual letters
out in the correct order so I can make them each correspond to a .gif
image to build a title.

Hope somebody can help!

An example please, since I still not clear to me what you are trying to
accomplish.

A string in an array of characters, you can access individual characters
like described in the fine manual:

I hope you are not using this for verification purposes, (Turing test). If
so, spammers will still be able to get parse each image if you are not
careful.

I have seen this done in Webmin. You might check their source code. I
don't think it is actually PHP (probably Perl), but it might give you
some good direction.

Ok, I have something working now, but with a few problems, my code is
below:

<?
// create a string ..
$txt = "My String Here";
$txt = strtoupper($txt );
// characters to search for
$txts = array ( "A", "B", "C", "D", "E", "F", and so forth );

// images array to replace them with.
$images = array ( "<img src=\"a.gif\" />", "<img src=\"b.gif\" />" ,
"<img src=\"c.gif\" />" , etc );
// continue with the <img src>'s with the number pattern above.

// Now, using str_replace to complete all the replacing.
$final = str_replace ($txts, $images, $txt);

echo $final;
?>

This works fine for my purpose, but, you will notice, I have to convert
my string to upper case characters for it to work. If the string is in
lower case, the str_replace function will replace all the characters in
the $images array as well.

Does anyone know a work around for this, so that i can use lower case
and upper case characters?

Thanks,

Duncan

echo $final;
?>

You could do away with your arrays by using backreferences and
preg_replace:

$final = preg_replace('/([a-zA-Z])/', '<img src="$1.gif" />', $string);

You would have to adjust things to work with spaces and other special
characters, but this would work with any letter.

This technique uses the GD library, which i can't use on my clients
host.
